Solving the Case: Anti-Fraud at the Start, I Signed In the Master Hacker

As far as you can see!

The safe door has been opened.

The door of the cabinet was even drilled and punched, clearly showing signs of violent damage.

Chen Ye stepped forward.

Check the traces carefully.

His expression became more and more serious.

Generally speaking.

Safes can be divided into six levels: A1, A2, B1, B2, B3, Class C, etc. according to the security level.

Each level is strictly graded.

Taking the A1 safety level as an example, the general standard is to prevent the use of ordinary hand tools, portable power tools and grinding heads and the mutual use of these tools to open the cabinet door within 15 minutes of net working time or cause 38 damage on the cabinet door and cabinet body. square centimeters of through holes.

Taking the highest class C safety level as an example, the general standard is to be able to prevent the use of ordinary hand tools, portable power tools, grinding heads and special portable power tools, cutting torches and explosives to open the cabinet door or in the cabinet within 60 minutes of net working time. Through holes of 13 square centimeters are formed on doors and cabinets, and their mass is not less than 450-kg.

The safe in front of him is obviously the highest grade C.

But it was dismantled like this.

Obviously unreasonable.

According to what Manager Zhang said, the entire black screen of the camera was only ten minutes.

The other party simply couldn't destroy it like this in such a short period of time.

Unless it is a super power drill.

or…

Chen Ye had a bold guess in his heart.

Li Zhiqiang and others came up.

Wang Weiguo asked, "Chen Ye, did you find anything?"

Chen Ye nodded, looked at Manager Zhang and asked, "If I read it right, this kind of safe should be a combination lock + mechanical lock, right?"

Manager Zhang hurriedly said, "That's right! Officer Chen, you are really amazing."

Saying that, he took out the key from his pocket.

He handed it over and said, "This is a mechanical key. You need to insert the key and turn it, and then enter the correct password before you can open the safe."

Li Zhiqiang asked, "Then Chen Ye, can you open this safe?"

Chen Ye shook his head and said: "Give me time, it will definitely be able to open, but this combination lock has precise mechanical gears inside, which is more difficult than ordinary mechanical locks! But the current direction is not this, I plan to check every gear. Traces, see if this safe is opened by password or by violence!"

Whoa!

Several people's expressions changed.

Li Zhiqiang asked, "Can you really be sure?"

Chen Ye said: "This is the beginning, and this is the end! These gears are very precise, which makes it difficult to open, but the same! Once opened by special means, it will inevitably leave traces on these precise gears, and these It's the evidence we locked down."

Li Zhiqiang immediately said: "Then you must first determine whether the safe is opened violently or through a password."

Chen Ye nodded.

He looked at Manager Zhang.

Manager Zhang consciously exited the door.

Chen Ye came to the safe.

squat.

Keep turning the knob with your right hand.

The whole person is attached to the outer wall of the safe and listens.

Gada!

Gada!

The crisp sound of gears turning.

Chen Ye listened attentively.

His expression gradually became strange.

Without him!

This combination lock has security in mind.

Combination code made of sixteen precision gears.

That is to say!

I want to open the cabinet door.

At least the sixteen-digit password needs to be fully verified.

But the difference in the sound of the gears in front of him is so subtle that even with his ability, he can't easily distinguish it.

Want to open!

It takes at least half an hour.

He opened the cabinet door again.

There is absolutely no trace of staggering on the gears.

He was worried.

Study the trajectory of each gear bit by bit.

ten minutes later.

He was sure he knew exactly what happened to the safe.

The surface of the door of this safe was violently dismantled, but it was actually opened directly through the password.

The suspect just wanted to deliberately mislead by this means!

He stood up and looked at Li Zhiqiang and Wang Weiguo Road: "Li team, master, it has been confirmed! This safe is opened by password + key."

Li Zhiqiang immediately asked, "Are you sure?"

Chen Ye nodded and said, "The suspect deliberately opened the door to induce us to handle the case. If Team Li feels that further inspection is needed, they can also ask the city bureau's unlocking experts to come and have a look."

Li Zhiqiang shook his head and said, "No need! Although I don't know about unlocking skills, just because you can easily open a C-level security door just now, your skills will definitely not be inferior to those of the experts from the Municipal Bureau. "

"It's just that this involves the choice of the direction of the investigation, and we must be cautious!"

Wang Weiguo also smiled and said, "That's right! Chen Ye, we are not suspicious of you. In fact, I have seen the two experts from the city bureau unlock the lock. Their speed is not as fast as you!"

Chen Ye said with a smile: "In that case, please let Team Li determine the direction of the investigation."

........ ask for flowers...  

Li Zhiqiang pondered: "At present, the suspect deliberately induces in this way, that is, we want our investigation direction to shift towards violent theft, and according to the inspection of the safe, this case is likely to be a combination of inside and outside, let's not go to it. the opponent's."

Wang Weiguo: "Then I'll call Manager Zhang in, and let's sort out the video again."

Chen Ye nodded and said: "This is a good way. This kind of safe door is made of stainless steel. If you want to destroy it like this, you need at least a high-power electric drill. I suggest you check the video in combination with this to see if it can help. Find."

Li Zhiqiang immediately said, "Go and call Manager Zhang in."

The king went out for the country.

Call Manager Zhang to come in.

Li Zhiqiang asked: "Is the bank monitoring still there?"

Manager Zhang said quickly: "I'm here, I'll take you there."

Li Zhiqiang hummed.

Several people came to the monitoring room on the third floor.

Li Zhiqiang asked: "Manager Zhang, there are some new changes in the case. I want you to describe the situation last night in full. At five o'clock last night, when you entered the warehouse, are you sure there is no problem with the safe?"

"If there is any concealment at this time and misleading our case, you should know the consequences!"

Manager Zhang shook his head like a rattle and said, "No, no, how dare I? When I went in yesterday, the safe was absolutely intact. Also, I wasn't alone at the time, and one of our tellers also went in with me. With cash, she can prove it."

Li Zhiqiang said: "What you said just now, we will further verify, Chen Ye, then start at five o'clock last night, check the monitoring situation, and focus on whether anyone has entered or exited the second floor with electric drills and other equipment."

Chen Ye nodded immediately.

next moment C

More than 20 cameras throughout the bank were all turned on.

16x speed playback!

Manager Zhang was taken aback by this scene.

He asked cautiously: "This... several police officers, can you really see clearly at such a fast speed?

Li Zhiqiang's face turned solemn, and he frowned, "Don't ask if you shouldn't ask!"

Manager Zhang's face collapsed.

I dare not ask more.

However, the expression on his face was clearly dissatisfied.

what the hell!

Obviously can't see anything.

This isn't going to be an act of pretense, is it?

Manager Zhang suddenly had this idea in his heart.
